Question
Find the y-intercept of the following equation.
y = –7x – 9
- -9
- -9x
- 5
- -5
Hint:
Constant part of standard equation y = mx + b , which is b is y intercept
The correct answer is: -9
We can write y = –7x – 9 as y=-7x+(-9)
The given equation is in slope-intercept form i.e., y = mx + b, where b is the y-intercept and m is the slope.
In y = –7x + (–9), the y-intercept b is –9.
put x = 0 , in the given equation and solve for y , you will get y intercept .
